Evaluate x + 2.7 for x= -1.5.
The value of the expression is
[tex]\text{x}=-1,5\\\\\text{x}+2,7=-1,5+2,7=2,7-1,5=\boxed{1,2}[/tex]
In a society there are 30 men and 20 women members.
What is the probability that the person selected for
the post of the president is a woman?
This is because there are 20 women out of 50 people total (30+20 = 50).
So 20/50 = 2/5
This converts to the decimal form 0.4 and the percentage form 40%
The Metropolitan Company sells its latest product at a unit price of $7. Variable costs are estimated to be 20% of the total revenue, while fixed costs amount to $6,300 per month. How many units
should the company sell per month to break even, assuming that it can sell up to 5,000 units per month at the planned price?
9514 1404 393
Answer:
1125
Step-by-step explanation:
The "contribution margin" of each product is 80% of its unit price, or $5.60. In order to break even, the total contribution margin must match the fixed costs.
$5.60n = $6300
n = 6300/5.6 = 1125
The company should sell 1125 units per month to break even.

A long distance runner does a first lap around a track in exactly 50 seconds. As she tires each subsequent lap takes 20% longer than the previous one. How long does she take to run 3 laps?
9514 1404 393
Answer:
182 seconds, or 3 minutes 2 seconds
Step-by-step explanation:
The second lap takes ...
(50 s)(1 +20%) = (50 s)(1.2) = 60 s
The third lap takes ...
(60 s)(1.2) = 72 s
The three laps take 50 +60 +72 = 182 seconds, or 3 minutes 2 seconds.
Explanation needed it the answer
Answer:
8 units
by step explanation:
Since AB and DC are parallel to each other;
Then x + 2x = 180°
3x = 180°
x = 180/3 = 60°
∆ABC = 60° and ∆ ADC = 120°
∆BAD = 60° (adjacent angles of a trapezoid add up to 180°)
As shown in the figure attached, part of line AB is equal to 3 units and part is equal to: (c) units * 2 .
[tex] \frac{c}{5} = \cos(60) = \frac{1}{2} [/tex]
c = 2.5 units
Hence length AB is equal to; 2(2.5) units + 3 units = 8 units

Step-by-step explanation:
the scale from a map to actual distance is 2.5 cm to 620 miles the distance on the map between Chicago and Boston is about 3.5 cm what is the distance between Chicago and Boston
Answer:
868 miles
Step-by-step explanation:
cm to miles ? are you sure you got the problem description right ? because cm are part of the metric system (mm, cm, meters, kilometers), while miles are part of American/ UK systems. and they don't deal with cm.
but ok, so, we will not deal with conversion rates, we will just apply the scale factors.
2.5 cm <-> 620 miles
3.5 cm <-> ? miles
that is determined by the factor to go from 2.5 to 3.5 cm. the same factor then had to be applied to the miles.
2.5 × f = 3.5
f = 3.5 / 2.5 = 7/2 / 5/2 = 7/2 × 2/5 = 7×2 / 2×5 = 7/5
=>
620 × 7/5 = 868 miles

Answer:
HJ = 13
Step-by-step explanation:
GH = x + 27 - (x + 24 )
GH = 3
GI = 6
GI = GH + HI
6 = 3 + 2x +25
2x = -22
x = (-11)
HJ = x + 24
= 24 - 11
= 13
